Backup Power Systems for Businesses & Homes in Cape Town
Load-shedding or power interruption doesn’t have to stop your day. SomeWatt Solar installs reliable, scalable backup power systems throughout the Western Cape — keeping lights on in homes, offices, retail spaces, and industrial facilities. Our hybrid inverter and lithium-battery solutions are designed to protect your power, reduce costs, and increase energy independence.
Why Choose a Backup Power System in Cape Town?
Energy instability has become part of daily life in South Africa. With our national grid under strain, even short power cuts can disrupt business operations and home comfort.
Backup power systems bridge this gap — ensuring you never lose productivity or peace of mind. SomeWatt Solar designs systems tailored for:
🏠 Homeowners who want reliable power and lower energy costs.
🏢 Businesses that depend on continuous uptime for operations or security systems.
🌾 Farms and remote sites where grid reliability is limited.
What Does a Backup Power System Include?
A backup system is made up of three essential components working together:
Hybrid Inverters
High-efficiency monocrystalline panels capture sunlight and convert it into usable electricity for your home. (JA, Canadian, Jinko)
Lithium Batteries
Quality inverters from Deye to transform solar energy into usable household current.
Switching & Monitoring Systems
Premium Dyness and Volta lithium batteries store excess power, keeping your home running smoothly during load-shedding.
How Backup Power Works
Your backup power system connects seamlessly with your existing electrical setup. When load-shedding or power outages occur, the inverter automatically switches to battery power — supplying stored energy to keep essential circuits running. Once grid power returns, the system recharges automatically.
Typical system setup:
Solar-ready hybrid inverter (Deye or Luxpower)
Lithium-ion battery pack (Dyness or Volta)
Optional solar panels for charging during the day
Backup Power for Every Need
| Application | Typical System Size | Use Case |
| Home (basic) | 5 kW inverter + 5 kWh battery | Lights, Wi-Fi, TV, fridge |
| Home (full) | 8 kW inverter + 10 kWh battery | Entire household backup |
| Business | 10 – 20 kW inverter + 15 – 30 kWh battery | Offices, workshops, retail stores |
